Summary:Title screen
The physical and mechanical principles governing aeroacoustic vibrations within a cylindrical channel have been established through a series of numerical experiments aimed at investigating the impact of multidirectional turbulent gas flow on the propagation of these vibrations. The developed physical and mathematical model has demonstrated its efficacy, as verification processes confirmed a strong correspondence between the results of numerical simulations, experimental findings, and existing literature data. This validation allows us to assert the reliability of the model and its potential for further research endeavors. The outcomes of the numerical experiments distinctly reveal that the amplitude of waves propagating upstream surpassed that of downstream and non-flow waves at equal distances from the acoustic source within the cylindrical channel. The results obtained were corroborated through comparison with experimental and relevant literature data. The identified influence of flow can be practically applied in cross-correlation analyses of the amplitude of aeroacoustic vibrations resulting from leaks in gas pipelines, thereby enhancing the accuracy of leak detection systems
